Enter a negative number to signify the end of the input. Assume that the maximum number of scores is 100 Here is a sample run: Enter a new score or negative number to exit: 99.1 Enter a new score or negative number to exit: 85.6 Enter a new score or negative number to exit: -1 Total scores entered: 2 Average score: 92.35 Number of scores above or equal to the average: 1 Number of scores below the average: 1 Flowchart; Begin // Comnanta Make Arraylsoores, 100 //Declarฉ ara ereate an array / Initialize aum accumlator to o // rnitia11ヱ숱 array îndax vwriab1 to D I91 inpue seareln Bcanner input tor tirat acoza 儿ーrr acore 1a negativa, ead the thile loop acoree Inoranent the arnay index vartable Input: sooreln /しーCat sart sooza uaing soanner input r acors ia nogative, and the wila 100p Exit Loop Total scores entered&i /LYes-Incrsnt the above counter Outpue: a new score or sepative nunber to exse alon Please send me your PreLab07 by next class to receive class participation credit.

import java.util.Scanner;

public class Test {

public static void main(String[] args){

Scanner in = new Scanner(System.in);

double scores[] = new double[0];

double score, sum = 0, avg;

int i = 0;

while(true) {

System.out.print("Enter a new score or negative number to exit: ");

score = in.nextDouble();

if(score > 100)

System.out.println("Score cannot be greater than 100");

else if(score < 0)

break;

else {

double[] temp = new double[scores.length + 1];

System.arraycopy(scores, 0, temp, 0, scores.length);

scores = temp;

scores[i++] = score;

sum += score;

}

}

System.out.println("Total Scores entered: "+ i);

avg = sum / i;

System.out.println("Average score: "+ avg);

int aboveAvg = 0, belowAvg = 0;

for(i = 0; i < scores.length; i++) {

if(scores[i] >= avg)

aboveAvg++;

else

belowAvg++;

}

System.out.println("Number of scores above or equal to the average:" + aboveAvg);

System.out.println("Number of scores below the average:" + belowAvg);

}

}
